Classic familial adenomatous polyposis, called FAP or classic FAP, is a genetic condition. It is diagnosed when a person develops more than 100 adenomatous colon polyps. An adenomatous polyp is an area where normal cells that line the inside of a personâs colon form a mass on the inside of the intestinal tract.
The most important factor used to measure a country's development is GNP. It is calculated by. adding up the values of all the goods and services produced in a country during the year. dividing the total by the number of people living in the country.
These measurements might affect the experimental response. It is useful to include these variables, called covariates, as design factors. Although you cannot directly control these values, you can ensure that the levels of the other design factors are chosen to yield the most precise estimates of all the effects.
